Application led December 4, i916. Serial No. 134,992.

frigerator which is improved. both in construction and operation.

YV ith the above and other objects in view, which will be more apparent as the description proceeds, the invention consists essentially in a refrigerator box having a closed bottom, a door, a top pan compartment and an air pipe leading from the compartment, a plurality of air lines contained within the box, passing through the bottoni of the refrigerator and communicating` with the top compartment, said flues forming the bounding walls of the cooling chamber, a water pan in the top compartment, absorbent fabric lining the flues, strips of absorbent fabric leading from the pan to the interior of the flues and shelves contained within the box between the fines, the parts being arranged and constructed as herein.- after more particularly described and later pointed out in the appended claims.l reference being had to the accompanying drawings in which :e

Figure 1 represents a vertical sectional view through a refrigerator embodying` my invention. Y

F ig. :2 represents a horizontal sectional view through my refrigerator.

Fig. 3 represents an enlarged detailed vertical sectional view through one of the flues showing the end receiving' tubes and the feeding strips.

Figa represents a perspective View of a fragmentary portion of one of the lines.

Referring` now to the drawings in which like characters of reference indicate corresponding parts in the several figures 1 represents a refrigerator box or outer casing of the usual form provided at the front with an entrance door 2 and supported on the corner legs 3 which are in the present instance actually extensions of the corner posts 3,

The box is provided with a closed bottom 4C and top 5 and is supplied with an internal horizontally disposed divisional plate'b which forms with the top and side walls of the box, a compartment 7 in which I insert a water pan 8. An air pipe 9 leads from the top of the pan compartment and in actual practice this pipe is connected with a chimney flue so that a good air draft can be had as later enlarged upon.

Nithin the box I locate two side fines l() and 11 and a back flue 12 which are identical in construction and are of such a size that they in reality form the inner walls of the refrigerator or in other words inclose the cooling` chamber.

Each flue is formed from a flattened metallic tube having the sides thereof'pierccd to provide a plurality of inwardly extending tongues or lips 13 which are adapted to obstruct the How of air passing through the lines.

The inner faces of the flues are lined with an absorbent material indicated at 14: and it. will be noticed that the tongues are pierced through this material so that actually when one views the interior of the lues he secs the lining with the tongues projecting through.

`W ith each i'iue I associate a pair of alined upright top and bottom flat tubes 15 and lb., the tubes 15 in each instance being lined with absorbent material 17 and being per manently secured to the divisional plate while the tubes 16 in each instance are permanently fastened to the bottom 4- of the box.

The flues are inserted in position within the box by first telescoping` the upper ends of the fines over the lower ends of the top pipes 15 which, it will be noticed, project below the divisional plate and then afterward inserting the lower ends of the fines into the upper ends of the bottom tubes and dropping` them until the side lugs 18 provided on the flues engage the upper ends of the latter tubes.

In this connection I wish it to be noted that sufficient clearance is provided at the lower ends of the upper tubes to allow the fiues to be slipped up far enough to admit of the easy insertion or withdrawal of the lower end of the flues from the lower tubes..

With such provision made it is a very easy matter to insert or remove the ues for cleaning or repair purposes.

The upper ends of the tubes 15 terminate above the top level of the pan 8 and they are provided on the pan side with cross slotsl 20 and with nipples or short tubes 21 which have their outer ends terminating adjoining outer ends passed through the slots 2O turnedV downwardly and bearing against the absorbent lining 17 of the tubes on Vthe side next the pan. Y Y

24A4 represents feeding strips of absorbent',I material passed through the nipples and hating their inner ends immersed in the water of the pan and their outer ends hanging down and bearing against the lining of the tubes remote from the pan.

Vith this arrangement it will be seen that the water in the pan is fed by capillary action by the strips 22 and 24 to the tube linings at both sides with the result that the tube linings are dampened as are also the linings of the flues. Y f Any dripping from the flues is passed down through the tubes 16 to the drip pan 2K5 located between the legs beneath the bottom of the box. Y j

A26, 27 and 2S represent refrigerator shelves inserted through the doorway into the 'cool-` ing chamber 29 and carried by sets of corner brackets 26, 27 and 28 fastened securely to the corner posts and extending inwardly between the adjoining edges of the flues.V

When this refrigerator is in use a strong air draft is effected through the lues, this draftv entering the flues at `the bottom, through the tubes 1G and escaping from the flues at the top through the tubes l5. Afterward it passes through the pipe 9 to the chimney flue. In passing upwardly through the flues the air draft is more or less arrested by theV tongues and in its passage is cooled by the evaporating water. The result is that the edible materialplaced in the refrigerator on the shelves is kept at a comparatively low temperature so that it is properly preserved without the use of ice as ordinarily occurs.

`I wish it to be particularly noticed in con- 1 A,V refrigeratorv depending upon thev principle of evaporation for the performance of its cooling function, Vcomprising an outer casing having a closed top and cottom and interiorly divided to present a top pan compartment and a lower cooling chamber, an air pipe leading'from'the top coinpartment, a water panwithin the top compartment, a plurality of alined vertically disposed flat tubes located adjacent the inner walls of the casing and projecting through the bottom of the top compartment VandV the -V bottomof the casing, aplurality of upstanding Vfahr-ic lined flues connecting the tubes in pairs and inclosing the sidesof the cooling chamber and Vstrips ofi-absorbent material immersed in the water of the pan and adapted to feed water by capillary action to the fabric lining of the ilues.V
